Noise from Audio/HVAC Controls (Reposition Audio Unit to Increase Clearance). Chevrolet Lumina Export 2007

Subject:

Noise from Audio/HVAC Controls (Reposition Audio Unit to Increase Clearance)

Models:

2007 Chevrolet Caprice, Lumina SS Models (Export)

Condition

Customers may comment on a creaking noise coming from the Audio/HVAC controls or the center vent/center console area.

Cause

This condition may be caused by contact between the edge of the Audio/HVAC fascia and the inner sides of the center console on all sports models.

Correction


(1)	Check for clearance along these gaps

Check for clearance by running a single piece of paper along the gap shown in the graphic above.


(1)	Check for clearance along this edge
(2)	Contact may occur at these "standoffs"; however, it will not cause noise due to isolation tape that is installed. The problem area is along the edge of the fascia.

The paper only needs to penetrate the gap to a depth of 5 mm (0.2 in) - any further and it may catch on "standoffs" behind the front face.

If paper does catch along length of gap, remove the audio fascia by pulling firmly towards the rear of vehicle at the bottom edge of the fascia.

With the radio fascia removed, locate the four screws (1) at the corners of the audio unit. Unscrew these by one to two turns and reposition the audio unit to relieve the contact condition. The design gap is only 0.5 mm (0.2 in), therefore only very slight movement of the audio unit is required.

Tighten the screws and reinstall the fascia to the audio unit. Check for clearance with paper and if contact occurs, repeat Steps 2 and 3 until there is a gap on both sides of the fascia.
